Abstract
Self-lubricating wear-resistant composite materials are produced by blending a metal powder matrix with a combination of molybdenum disulfide and tungsten disulfide powders, compression-molding the blend and then sintering the molding at 800.degree. to 1000.degree.C. When the combination of molybdenum disulfide and tungsten disulfide is blended with a metal powder matrix as described above, the molybdenum disulfide reacts with the metal powder matrix and consequently reinforces the metal matrix and the tungsten disulfide is dispersed as a lubricant element in the resultant composite material, giving rise to a composite material excellent in mechanical strength and lubricating property.
